GEF - GDB Enhanced Features

GEF (pronounced ʤɛf - "Jeff") is a kick-ass set of commands for X86, ARM, MIPS, PowerPC and SPARC to make GDB cool again for exploit dev. It is aimed to be used mostly by exploit developers and reverse-engineers, to provide additional features to GDB using the Python API to assist during the process of dynamic analysis and exploit development.

It has full support for both Python2 and Python3 indifferently (as more and more
distros start pushing gdb compiled with Python3 support).

Some of GEF features include:

One single GDB script.

Entirely OS Agnostic, NO dependencies: GEF is battery-included and is installable in 2 seconds (unlike PwnDBG).

Fast limiting the number of dependencies and optimizing code to make the
commands as fast as possible (unlike PwnDBG).

Provides more than 50 commands to drastically change your experience in
GDB.

Easily extendable to create other commands by providing more comprehensible
layout to GDB Python API.

Works consistently on both Python2 and Python3.

Built around an architecture abstraction layer, so all commands work in any
GDB-supported architecture such as x86-32/64, ARMv5/6/7, AARCH64, SPARC, MIPS,
PowerPC, etc. (unlike PEDA)

Suited for real-life apps debugging, exploit development, just as much as
CTF (unlike PEDA or PwnDBG)

Just make sure you are using the pip corresponding to the version of Python
your GDB was compiled with. If you are experiencing issues installing them,
post an issue on the GitHub of the respective projects. If your bug is not
related to GEF, you will not get an answer.

Additional commands

GEF was built to also provide a solid base for external scripts. The
repository gef-extras is an open
repository where anyone can freely submit their own commands to extend GDB via
GEF's API.

Bugs & Feedbacks

To discuss gef, gdb, exploitation or other topics, feel free to join the
##gef channel on the Freenode IRC network. You can also talk to me (hugsy) on the
channel. For those who do not have an IRC client (like weechat or irssi),
simply click here.

For bugs or feature requests, just
go here and provide a thorough description
if you want help.

Side Note: GEF fully relies on the GDB API and other Linux-specific sources
of information (such as /proc/<pid>). As a consequence, some of the features
might not work on custom or hardened systems such as GrSec.
